Where do I find prefabs?

I was reading the Introduction to the Unity Interface tutorial pdf , and was able to follow everything pretty well up until I reached Section 9, Using Assets. There it says I have to expand the Standard Assets folder, and then the prefabs, and they'll I'll see the First Person Controller (FPS Controller). However the folder is empty, and everywhere I look, I can't find anything that resembles the FPS Controller. I'm not sure if its somewhere blatantly obvious, or if I have to download it from somewhere, but whichever it is I have no idea.

Please help

I remember that the tutorial was done with unity 2.6. Unity 3.0 changed a few things. First of all, make sure you select the Character Controller unity package when creating a new Unity project.

Hold the alt key while starting Unity and under Create New select the Character Controller.
